Future COVID variants likely to infect us differently: Expert explains why
Omicron variant are less likely to spread the virus to others if they have been vaccinated or have had a previous SARS-CoV-2 infection.
And in case, the individual has taken both doses of vaccines then the chances of spreading the virus are even lesser. The study was posted as a preprint on medRxiv this month and has not been peer-reviewed.
Noting it to be good news, Steain told scientific journal Nature, the more exposure people have to the virus, whether through vaccines, boosters or infections, the “higher the wall of immunity", she says. “If we can keep high levels of booster vaccinations up, then we can decrease how infectious people are when they’re sick." The study was led by Nathan Lo, an infectious-disease researcher at the University of California, San Francisco, and his colleagues who analysed data of more than 22,000 confirmed cases of SARS-CoV-2 infection across California’s 35 adult prisons over a 5-month period during the first wave of the Omicron virus.
The wave started with the BA.1 subvariant, but by the end of April, BA.2 had overtaken it and was the most common cause of COVID-19 in the country.
